Dexterity Jane

How fast can you bend your fingers?
Dexterity Jane is back in town. She enters the saloon and sits down at a gambling table. In search of fame, some brave cowboys approach and dare to challenge her. The game begins and already hands are flying, phalanxes are bending and unfolding at a frantic pace. Cautious, the onlookers move back a step. The less resistant ones crack and collapse, while Dexterity Jane seems insensitive to the pressure. This time again she will leave victorious, crowned with an unequalled fame.
How the game works
Look at the cards spread out on the table and fold the required fingers as quickly as possible. Dexterity Jane is a game of speed that combines observation and dexterity. At the beginning of each round, reveal as many hand cards as the current round number. Each card shows a left or right hand with no more than one finger bent. Immediately, all players begin to bend their fingers according to what is called for by the revealed Hand cards.

        If several cards show different fingers to be bent on the same hand (left or right), bend them all.
        If the same finger is to be folded twice, cancel this action, leaving it unfolded.
        If a fully open hand is revealed, it cancels all other Hand cards indicating to fold a finger on that hand.
        If two of the same open hands (left or right) are revealed, they cancel each other out.


After this step, lock your hands on the table by turning them over. Be careful: if a hand does not have a folded finger, you must place the fist on the table, not a flat hand turned over!
How to win?
All players who have folded their fingers correctly win a card worth 1 point. The first player to have locked his hand wins the tile of the current round, worth as many points as its value.

Thus, in the 1st round, 1 hand card is drawn and the hand tile is worth 1 point, in the 2nd round 2 cards are drawn and 2 points are at stake, and so on until the 10th round, when 10 cards must be analyzed as quickly as possible to earn 10 points!
